How to grow watermelons without seeds

Watermelon seeds are the seeds of watermelons, but watermelons without seeds have no seeds, so do you know how to grow watermelons without seeds? Let's take a look at it next.

First, buy seeds

Seedless watermelon is a special watermelon produced by crossing diploid watermelon and tetraploid produced by mutagenesis. You can buy seeds directly on the market, and you can buy a bag for about a few dozen yuan. Select seeds with similar color and luster and full individuals to soak, and then use natural drying after soaking. The seeds of seedless watermelon also need to be treated by artificial shell breaking, which is convenient for it to germinate, and there are also two ways to break the shell. At present, the wet seed shell breaking method is commonly used, that is, after soaking, the shell breaking operation is carried out. It has a relatively high germination rate, and it is also easy to operate.

Second, sowing seeds

After breaking the shell, it can be germinated at a stable temperature. after 24 hours of indoor culture, it can generally sprout, and those that sprout more than one centimeter can be selected for sowing. Under normal circumstances, all seeds will sprout within two days. Beyond this time is basically a bad seed and will not sprout again.

Third, budding management

It is a very critical period from seed germination to unearthed, so it is necessary to strengthen management during this period, especially during this period, the temperature is very high, which generally needs to be controlled at about 35 degrees during the day and above 25 degrees at night. If the seedlings begin to arch the soil, remove the film immediately, and then provide some urea appropriately to help the seedlings grow. Ethephon can be used to assist growth during the growth period.

Fourth, leave the melon

When the melon seedlings grow to a certain degree, it is necessary to pick the vines, remove the long whiskers from the main vines, and make the watermelons grow better. In the process of growing, watermelons should leave a melon vine every 2 to 3 nodes. After the selection is completed, it is necessary to leave 2 melons on each side vine and remove the melons that are not in good shape, deformed and flat.

V. Harvest

Watermelons will stop growing when they have grown enough days. According to the specifications of the varieties, watermelons can be irrigated with manure before harvest to improve the quality of watermelons. The time for sale must be selected. The time is too early for watermelons to mature, and too late will also affect the quality of watermelons. After harvest, clean up the watermelon land and sprinkle it on the ground with farm manure. Do a good job of raising the land for sowing in the coming year.

Planting seedless watermelons is similar to seeded watermelons. Seedless watermelons are more expensive and profitable. If conditions permit, seedless watermelons can be planted.
